Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The question asks to identify the disease caused by a lack of iron in the diet.
Step 2: Detailed Explanation:
(C) Anaemia: Iron is a crucial component of hemoglobin, the protein in red blood cells that carries oxygen from the lungs to the rest of the body. A deficiency of iron leads to a decrease in hemoglobin production, resulting in a condition called iron-deficiency anaemia. Symptoms include fatigue, weakness, and shortness of breath.
The other diseases are caused by different nutrient deficiencies:
(A) Night blindness: Caused by a deficiency of Vitamin A.
(B) Beriberi: Caused by a deficiency of Vitamin B1 (Thiamine).
Step 3: Final Answer:
Iron deficiency causes Anaemia.
